Section 12. Program Control Instructions
12-9
This instruction is not necessary in networks with wireless sensors and only
one Master datalogger, because the Wireless Network Master (P193) and
Wireless Network Remote (P196) instructions perform these functions
automatically.
This instruction can also be used to remove a datalogger from the PakBus
network.
3: PakBus - Send Message (P192)
1: 00 Port
2: 0000 Address
3: 2 Clock Report
Message Type
Entry Description
2 Clock report; sends the current time.
13 The datalogger that receives this message will remove the sending
datalogger from its neighbor list (and therefore all links to the sending
datalogger).
Wireless Network Master (P193)
A program control instruction that is used to prepare the local datalogger to
send data to or receive data from one or more dataloggers/wireless sensors in a
PakBus network. The instruction also assigns a transmission time to the remote
dataloggers/wireless sensors. Instruction 193 does not actually initiate the
transfer of data. Data transfer is initiated by the wireless sensor.
Multiple Instruction 193s can be used in a program to configure up to four
different groups of dataloggers/wireless sensors. A "group" is determined by
the First Remote Address and the Number of Remotes. A datalogger/wireless
sensor can only belong to one group. An error message will occur (E81) if a
datalogger/wireless sensor is assigned to more than one group.
4: PakBus - Wireless Network Master (P193)
1: 00 Number of Remotes
2: 0000 First Remote Address
3: 0000 Time Into Transmit Interval (sec)
4: 0000 Transmit Interval (sec, 0 = use execution interval)
5: 00 Transmit Delay Between Remotes (sec)
6: 00 Swath to Receive
7: 0000 First Loc for Data Received [ ______________ ]
8: 00 Swath to Send
9: 0000 First Loc to Send [ ______________ ]
10: 0000 Result Code Loc [ ______________ ]
Notes:
The wireless sensors will actually begin transmitting before the specified
transmission time (based on Time Into Transmit Interval and Transmit Interval)
so that transmission is complete when the specified transmission time occurs.
The Transmit Delay Between Remotes is factored into to the transmit time
assigned to each remote.
